An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship.
Serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
AEs included both SAEs and non-serious AEs.

Measure Description |
Time Frame |

|
Double-Blind Period: Relapse Rate: Total Number of Confirmed Relapses
Time Frame: Baseline (Week 0) up to end of active double-blind phase or termination/early termination visit (up to Week 36)
|
Relapse was defined as the appearance of one or more new neurological abnormalities or the reappearance of one or more previously observed neurological abnormalities, lasting for at least 48 hours (in the absence of fever or any infection) and immediately preceded by an improving neurological state of at least 30 days from onset of previous relapse.
An event was counted as a relapse only when the participant's symptoms were accompanied by observed objective neurological changes, consistent with an increase of at least 0.5 in the Expanded disability status scale (EDSS); or one grade in the score of 2 or more of the 7 Functional Systems (FS) (excluding changes in bowel or bladder function or cognition); or 2 grades in the score of one of the FS as compared to the previous evaluation.
EDSS assesses disability in 8 functional systems with an overall score ranging from 0 (normal) to 10 (death due to multiple sclerosis [MS]).
|
Baseline (Week 0) up to end of active double-blind phase or termination/early termination visit (up to Week 36)

Double-Blind Period: Number of Enhancing Lesions on T1-Weighted Images
Time Frame: At the end of active double-blind phase or termination/early termination visit (up to Week 36)
|
Inflammatory disease activity was assessed by magnetic resonance imaging (MRI) measurement of the number of gadolinium-enhanced T1 lesions.
T1-weighted scan was taken after administration of gadolinium-gadopentetic acid (Gd-DTPA).
|
At the end of active double-blind phase or termination/early termination visit (up to Week 36)

|
At the end of active double-blind phase or termination/early termination visit (up to Week 36)
|

Time Frame: At the end of active double-blind phase or termination/early termination visit (up to Week 36)
|
Inflammatory disease activity was assessed by MRI measurement of the number of new hypointense T1 lesions.

Double-Blind Period: Kurtzke's Expanded Disability Status Scale (EDSS) Score
Time Frame: At the end of active double-blind phase or termination/early termination visit (up to Week 36)
|
EDSS (developed by John F. Kurtzke) is a scale for assessing disability in 8 functional systems (visual, brain stem, pyramidal, cerebellar, sensory, bowel and bladder, cerebral, and other functions).
Each functional system score and an overall score ranges from 0 to 10, where 0 = Normal; 1-1.5 = No disability, but some abnormal neurological signs; 2-2.5 = Minimal disability; 3-4.5 = Moderate disability, affecting daily activities, but can still walk; 5-8 = More severe disability, impairing daily activities and requiring assistance with walking; 8.5-9.5 = Very severe disability, restricting to bed; 10 = Death due to MS.
A lower score indicated less disability.
